99.5 Digital (Guaymas)

Digital 99.5 FM (XHDR-FM) is a radio station in Guaymas, Sonora, broadcasting on 99.5 with a regional Mexican format known as La Patrona. It is locally owned by Grupo Radio Guaymas.

The station's history dates to 1938, when XEDR received its first concession as the first radio station in Guaymas. It was owned by Modesto Ortega and broadcast on 1490 kHz. By the 1960s, Ortega had died and his successors owned the station.

An FM combo, XHDR-FM 99.5, was added in 1994. In the mid-2000s, the AM station moved from 1490 to 830 kHz, changing from 1 kW day/0.25 kW night operation to offer 2.5 kilowatts of power during the day.

In 2012, after decades of ownership by Ortega's successors, the station was sold to Radio Amistad de Sonora, owned by the Lizárraga Verdugo family. In a letter dated December 11, 2017, Radio Amistad de Sonora told the Federal Telecommunications Institute it would not renew the AM station, leaving XHDR as an FM-only operation.
